Great to know, and good point. From that perspective, a Steam/Linux project would be in the same category as an iOS or Mac app: ABI stability doesn’t matter, so long as you include a copy of the swift standard library along with the steam app itself. I know nothing about Steam, but it seems likely that this would have been a requirement anyway, because you can’t count on the standard library already existing.
ABI stability starts to matter when you’re interested in combining precompiled libraries built by different parties, which are only distributed in binary form.
